Indoor Unit Size(s) Mini split systems can have one or more indoor units connected to a single outdoor unit. Indoor Unit Size(s) specifies what indoor unit sizes are used in a system. For example (09 + 12) means the system includes a 9k BTU unit and a 12k BTU unit.

Mitsubishi's dedication to new technology means that multi-zone mini split systems are now a year-round comfort solution for homes in freezing climates. This low ambient system uses a Hyper-Heating H2i MXZ-4C36NAHZ outdoor condenser to provide efficient cooling and subzero heating through three advanced MSZ-FH wall mounted indoor units. These indoor units feature Mitsubishi's i-See sensor, which automatically detects where heating or cooling is needed. Three wireless remote controllers guarantee convenient comfort by allowing you to control the temperature in individual rooms. With multiple operating modes, multiple fan speeds, and multiple airflow directions, this is a system that fits the needs of nearly any home.

Product Features

H2i TechnologyLow and negative ambient temperatures don't bother the MXZ-4C36NAHZ. It is rated for 100% heating capacity at 5° F and continues to provide heating in outdoor conditions as low as -13° F.

Integrated Base Pan HeaterMXZ-C outdoor condensers have a factory-installed base pan heater in the drain pan. This prevents condensate from freezing and damaging the unit in frigid climates.

Precision Temperature Control TechnologyThis condenser is equipped with advanced inverter technology. By adjusting compressor speed and refrigerant flow, these components match the output of the condenser to the active zones. This provides precise temperature control and incredible efficiency.

i-see SensorEach MSZ-FH indoor unit has an i-see Sensor 3D that monitors its zone for changes in temperature and occupancy. If an underserved area is detected, an MSZ-FH will temporarily adjust airflow to ensure complete comfort throughout the zone.

Occupancy SensorMitsubishi's i-see technology can also detect a room's current occupancy. Through the use of targeted airflow, and adjusting the temperature of an empty room, the i-see sensor will conserve energy and save you money.

Advanced Filtration SystemWith three unique filters inside the MSZ-FH indoor units, the air in your zones is not only being conditioned, but it is also actively being cleaned. Three levels of filtration will keep foul odors and harmful bacteria from floating around your home.

Smart SetMitsubishi's Smart Set function allows you to save a comfort profile consisting of a temperature down to 50° F, fan speed, and airflow direction for each indoor unit. These profiles can be activated with a single press of the Smart Set button.

Powerful ModeThe powerful setting on an MSZ-FH indoor unit makes it easy to get your zones to the perfect temperature quickly. When it is activated, a unit temporarily increases refrigerant flow and fan speed to provide quick comfort through rapid heating or cooling.

Econo Cool ModeBy slowly adjusting the cooling set point and swinging the horizontal vanes, an MSZ-FH mini split indoor unit can improve the efficiency of cooling operations without compromising the comfort provided.

DehumidificationWhen the indoor unit is run in dry mode, it will remove extra moisture from the room. This improves your comfort and reduces both mold growth and the chance of property damage in the conditioned space.

Vane ControlOptimal air flow is easy with Mitsubishi's MSZ-FH mini split indoor units thanks to the vane control option. This provides five horizontal vane positions, an auto mode, and a swing mode. Four way vane control helps provide unmatched comfort.

Q: When the room units are hung is it necessary to have holes through to the exterior of the house?by Kevin B. from New York on August 07, 2016

A: For each indoor unit, both line sets and connecting wire must run back to the outdoor unit, so a hole to the exterior is necessary. You can make a penetration for each indoor unit, or you can make a single larger penetration centrally (near the outdoor unit) to fit all the required pipes and cables. You can seal the hole(s) afterwards. by Chris, Product Expert

Q: What is hyper heating?by Dan P. from Texas on August 05, 2016

A: Hyper-Heating (also called H2i) is Mitsubishi's low-ambient temperature (outdoor temperature) heating technology. H2i units are capable of delivering nearly 100% of their rated heating capacity down to 0° F, and are capable of running in temperatures as low as -13° F. by Chris, Product Expert
